Bidding of price taker power generators in the deregulated Turkish power market
(Pergamon-Elsevier Science Ltd, 2013)In deregulated power markets power firms bid into the day-ahead power market either with buy offers or sell offers. The auction mechanism and competition determine the equilibrium price and quantity for each hour. If the ... -
Computing trade-offs in robust design: Perspectives of the mean squared error
(Pergamon-Elsevier Science Ltd, 2011)Researchers often identify robust design as one of the most effective engineering design methods for continuous quality improvement. When more than one quality characteristic is considered an important question is how to ... -
Cosmic ray intensity variation during a CME
(Pergamon-Elsevier Science Ltd, 2002)The June 6 2000 coronal mass ejection was an exceptional full halo which made it possible to measure cosmic ray (CR) decrease with a simple experimental set-up. Variation in the local secondary cosmic ray density has been ... -
Derivation of the optical constants of spin coated CeO2-TiO2-ZrO2 thin films prepared by sol-gel route
(Pergamon-Elsevier Science Ltd, 2011)Ternary thin films of cerium titanium zirconium mixed oxide were prepared by the sol-gel process and deposited by a spin coating technique at different spin speeds (1000-4000 rpm). Ceric ammonium nitrate ce(NO3)(6)(NH4)(2) ... -
Docking studies on monoamine oxidase-B inhibitors: Estimation of inhibition constants (K-i) of a series of experimentally tested compounds
(Pergamon-Elsevier Science Ltd, 2005)Monoamine oxidase (EC1.4.3.4 -
A framework for water and carbon footprint analysis of national electricity production scenarios
(Pergamon-Elsevier Science Ltd, 2017)While carbon footprint reduction potential and energy security aspects of renewable and non-renewable resources are widely considered in energy policy their effects on water resources are mostly overlooked. This research ... -
A heuristic approach for allocation of data to RFID tags: A data allocation knapsack problem (DAKP)
(Pergamon-Elsevier Science Ltd, 2012)Durable products and their components are increasingly being equipped with one of several forms of automatic identification technology such as radio frequency identification (RFID). This technology enables data collection, ... -
A historical assessment of Turkey's natural gas import vulnerability
(Pergamon-Elsevier Science Ltd, 2018)This article aims at evaluating the historical determinants and implications of Turkey's natural gas import dependency. We implement principle component analysis (PCA) methodology to construct a natural gas import vulnerability ... -
A hybrid approach to concept selection through fuzzy analytic network process
(Pergamon-Elsevier Science Ltd, 2009)Evaluating conceptual design alternatives in a new product development (NPD) environment has been one of the most critical issues for many companies which try to survive in the fast-growing world markets. Therefore most ... -
Leveraging saving-based algorithms by master-slave genetic algorithms
(Pergamon-Elsevier Science Ltd, 2011)Saving-based algorithms are commonly used as inner mechanisms of efficient heuristic construction procedures. We present a general mechanism for enhancing the effectiveness of such heuristics based on a two-level genetic ... -
Master problem approximations in Dantzig-Wolfe decomposition of variational inequality problems with applications to two energy market models
(Pergamon-Elsevier Science Ltd, 2013)In this paper a modification to Dantzig-Wolfe (DW) decomposition algorithm for variational inequality (VI) problems is considered to alleviate the computational burden and to facilitate model management and maintenance. ... -
A memetic random-key genetic algorithm for a symmetric multi-objective traveling salesman problem
(Pergamon-Elsevier Science Ltd, 2008)This paper proposes a methodology to find weakly Pareto optimal solutions to a symmetric multi-objective traveling salesman problem using a memetic random-key genetic algorithm that has been augmented by a 2-opt local ... -
Minimization of rest mismatches in round robin tournaments
(Pergamon-Elsevier Science Ltd, 2018)In sports tournaments an occurrence of a difference in the rest periods of opponent teams in a game which we refer to as a rest mismatch will disadvantage the less rested team. Thus it is only fair to expect opposing teams ... -
Models for relief routing: equity efficiency and efficacy
(Pergamon-Elsevier Science Ltd, 2012)In humanitarian relief operations vehicle routing and supply allocation decisions are critically important. Similar routing and allocation decisions are studied for commercial settings where efficiency in terms of minimizing ... -
Molecular modifications on carboxylic acid derivatives as potent histone deacetylase inhibitors: Activity and docking studies
(Pergamon-Elsevier Science Ltd, 2009)In the light of known HDAC inhibitors 33 carboxylic acid derivatives were tested to understand the structural requirements for HDAC inhibition activity. Several modifications were applied to develop the structure-activity ... -
New pyrazoline bearing 4(3H)-quinazolinone inhibitors of monoamine oxidase: Synthesis biological evaluation and structural determinants of MAO-A and MAO-B selectivity
(Pergamon-Elsevier Science Ltd, 2009)A new series of pyrazoline derivatives were prepared starting from a quinazolinone ring and evaluated for antidepressant anxiogenic and MAO-A and -B inhibitory activities by in vivo and in vitro tests respectively. Most ... -
The operational economics of compressed air energy storage systems under uncertainty
(Pergamon-Elsevier Science Ltd, 2013)A Compressed Air Energy Storage System is a means of storing energy which can then be used when the demand for energy increases. In this system air is compressed in a cavern when power prices are low and this air is used ... -
